Your oblique muscles are part of the entire picture of your core. Oblique muscles are crucial to core strength. They help you bend side to side, rotate right and left, and stabilize and protect your spine. Your oblique muscles work in harmony with all of your abdominal muscles to truly give you a tight tummy and a strong, stable back.

If you want flat abs you need to look at the whole picture. Good eating, regular fat-burning cardio, and strength training are all-important.

But the core exercises you do need to be all-inclusive. Many middle-aged people complain about having a “muffin top” or that extra layer of fat that spills over the waistline of a pair of jeans. Getting rid of a muffin top requires that all-inclusive picture of eating right, exercising regularly, and doing well-rounded core moves.

What are Oblique Crunches?

An oblique crunch is a core exercise that strengthens your obliques as well as the other muscles of the core including your transverse abdominus and medial glute. Many ab exercises focus solely on the rectus abdominus, also known as the six-pack.

While important, it is also wise to focus on strengthening the rest of the core muscle group so that your strength is balanced. If you learn how to do an oblique crunch, you will feel it in your waistline the next day!

Time needed: 2 minutes.

  1. Begin by lying on your side, forearm down, knees bent slightly.
  2. Roll slightly back onto your glute, like you’re sitting on the back pocket of your jeans, and lift legs a few inches off the mat. Bring the top hand behind the head so the elbow is also bent.
  3. Lift your legs up bringing your knees to your elbow while at the same time crunching your elbow toward your knee. Squeeze your waistline with each lift. Perform the desired number of reps and switch sides.

How Many Calories Does An Oblique Crunch Burn?

eople often ask how many calories they are burning in their workouts. Most exercises will generally burn about 100 calories for every 10 minutes you are working at a higher intensity. Bottom line – the harder you work, the more calories you burn.

The oblique crunch is meant to strengthen the core and though you will burn calories during strength training, remember that you also burn more calories throughout the day when you have more muscle mass.
